2026 Great Britain 1 oz Gold Britannia | £100 | .9999 Fine Gold | Royal Mint Bullion Coin

Description:
The 2026 Great Britain 1 oz Gold Britannia continues the Royal Mint’s iconic flagship bullion series — a symbol of strength, security, and heritage. Struck in .9999 fine (24-karat) gold, each coin features the timeless image of Britannia, the female personification of Britain, standing firm against the wind with shield and trident in hand.

Renowned for both its artistry and advanced security technology, the Gold Britannia integrates four innovative anti-counterfeit features — including micro-text, surface animation, latent imagery, and intricate background detailing — ensuring the coin’s authenticity and purity.

The obverse bears the official effigy of His Majesty King Charles III, designed by Martin Jennings, marking the second year of the King’s portrait on the Britannia series.
